Windows10 Build Fails: colcon build TypeError

[hpeng-kcl]

Hi, I am here to seek some help for ROS2 colcon error in Windows 10. I was trying to run the tutorial in ROS2 "Using colcon to build packages" , while I input the command "colcon build --symlink-install --merge-install", the command window shows the error:

"Summary: 16 packages finished [5min 45s] 7 packages had stderr output: examples_rclpy_executors examples_rclpy_minimal_action_client examples_rclpy_minimal_action_server examples_rclpy_minimal_client examples_rclpy_minimal_publisher examples_rclpy_minimal_service examples_rclpy_minimal_subscriber WNDPROC return value cannot be converted to LRESULT TypeError: WPARAM is simple, so must be an int object (got NoneType)"

I was trying to solve this "WNDPROC return value cannot be converted to LRESULT TypeError: WPARAM is simple, so must be an int object (got NoneType)", but didn't find a way out, can you please give me some resolution or hints to fix this?

Hi @hpeng-kcl The RealSense ROS2 wrapper is difficult to get working successfully on Windows 10 and can involve multiple steps and file installations. The best reference for doing so is at #2660

Hi Marty! Thank you so much for reply the issue! I have resolved the issue by using another installer to reinstall the ROS2 in win10 and win11, now both win10 and win11 are working well.
